A suitable long and relatively narrow bunchvor tutt of bristles is assembled and dipped in a heavy solution of rubber cement, the bunch being about half the length of one of the long grooves and being a little thicker than theopening of the throat and in a, 'manner more. QfullyA described thin rubber cement'is 4preferablyv placedv in loo having itsbutts pressed together by a vise or otherwise. The butt-s ofrthe bristles 'of the bunch are then inserted into, and against the base of, a groove or channel whereupon the butts spread apart. I then press, with a knife or other suitable tool, against one end of the bunch and then against the other, `forcing the bunch very compactly together` longitudinally. this pressing and forcing tending to spread apart the ends of the bristles within the groove and transversely thereof with the result that said ends hold with great firmness with a short hold within the groove, thereby providing great fiexibility for the bristles in use, the cement, after vulcanization. adding to such holding. I prefer to .first insert a bunch of bristles about half the length ot the groove. as shown in Figure 9, and after this has been pressed together I insert a similar bunch and when this has been pressed together I may insert smaller bunches, such as that shown in Figure 8, to completely fill the groove longitudinally. Bunches are similarly inserted in all the grooves and in the grooves between the plate 6 and the terrule. Vulcanizing is then had and during it the cementin said spaces is pressed above the casing and iirmly binds the bristles to the casing, the bottom of the casing being pref erably slightly below the bottom of the holder and curving slightly at 16 inwardly to grip the bristles, the member 6 being bent as shown in Figure l so that the channel between the casing and holder is wider at the base than at the throat.

that I claim is:

1. A brush comprising a casing; a channeled bristle carrying holder arranged within the casing; eyelet rivets connecting the casing and holder; and spacing washers surrounding` the rivets between the casing and holder.

2. A brush comprising aV handle; a casing; a bristle carrying holder ar anged within the casing; tubular rivets fastening the casing and holder together in fixed relation; and screws extending through said tubular rivets into said handle. y

3. A brush comprising a casing; av bristle holder within the casing and having a plurality of channels in which the bristles are anchored; eyelet rivets connecting the casing and holder; and spacing washers surrounding the rivets between the casing and holder; said washersiand rivets being disposed bctween said channels.

4. In a brush, a bristle carrying holder, a easing spaced from the holder, bristles secured in said space, said casing having a portion extending below the bottom of the holder and gripping the bristles in said space.

5. The combination of' a bristle holder having a plurality of channels to receive bristles within them, said channels being tixedly spaced apartwith relation to each other and each having a base and two side walls; a casing within which said .holder is arranged; and means to hold the holder and casing rigidly together.

(i. The combination ol a. bristle holder made of sheet metal and having a plurality of channels to receive bristles wit-hin them, each channel having a base and two side walls; a metal casing within which said holderis arranged; and means to hold the holder and casing rigidly together.

l'. A brush comprising a casing; ay bristle carrying holder arranged within the casing and having a plurality ot channels, each channel having a base and two side walls, said holder also comprising a portion oonnecting adjacent channels and spacing them trom each other transversely ot the brush, said portion being spaced from the casing; means to hold said portion spaced from the casing; and means to hold the casing and holder together. y

8. A brush comprising a channeled holder, the walls of the channel being fixed relatively to each other; bristles having their butts seated in the channel; means closing the ends of the channel to confine the butts in the channel; a casing within which the holder is arranged, the ends ol' the casing being spaced from said closing means; and bristles secured in the space between the holder and the casing. l
